Answer:
n = -1
Step-by-step explanation:
1 - 8n - 8 = -7n - 6n - 12
Simplify
-8n - 7 = -13n - 12
Add 7 to both sides
-8n = -13n - 5
Add 13n to both sides
5n = -5
Divide both sides by 5
n = -1
A trick that is good for multiplying 9's is, remember that each time the tens digit changes the number in the ones spaces minuses 1. If you don't understand what I am saying look at the following:-
9
18
27
36
45
54
63
72
81
See the pattern? In the tens place you need to add 1 and in the tens place you need to subtract by 1.
Hope I helped ya!! xD

Answer:
for n=2, f(2)=f(1)*(-1/2) we know that f(1)= -16 so put it
f(2)=(-16)*(-1/2)=8
then put n=3 so f(3)=f(2)*(-1/2)
f(3)=8*(-1/2)= -4
